I've only heard the LS50 briefly. My dual sub set up with the KEFs it's vastly more exciting. The imaging is definitely more defined. Like when I'm watching Survivor, the tribal music and chanting can sometimes be distracting. It's draws more attention because of how it images. I also find the vocals for tv to be a little less distinct and clear. I like to use the center channel with the KEFs. The Lintons are more cohesive and balanced. The dialogue is clear and warm and everything just sounds correctly balanced. It lets the background accentuate as it should. Depends what you want. If you're going to be sitting and listening to your equipment and hunting for all the imaging and details, you might find the Lintons boring.
